It is an oxidizing agent that, by virtue of its accepting electrons, is itself reduced in the process. In anaerobic respiration, nitrate, sulfate, or sulfur act as the terminal electron acceptor. So pyruvate can neither “take the place of O 2 as the final electron acceptor”, nor would there be any point in modifying this complex machinery just so that it could be used by pyruvate to regenerate NAD + when a single cytoplasmic enzyme (lactate dehydrogenase) will do the job. The final electron acceptor in aerobic respiration is oxygen, according to McGraw Hill Education. A final electron acceptor is a molecule that accepts an electron at the final stage of an electron transport chain.
